Geological Maps

Geoscience and GIS

Exploration of the Earth’s subsurface requires a team approach, and increasingly team members are using collaborative, integrated workflows and methodologies that combine all 4Gs – geology, geophysics, geochemistry and GIS (geographic information systems) to unravel their discovery challenges.

Modern mapping software, and improved exploration workflows for GIS are helping to conduct advanced interrogation of data from multiple perspectives, for more accurate interpretation results. Exploration software now supports a more integrated workflow for subsurface investigations across exploration systems and GIS - from importing the data, through to quality control, analysis, and integration of other datasets and finally to visualization in a way that is meaningful to colleagues, managers and industry stakeholders. 3D visualization software also supports the integration of different types of datasets, including geoscientific data, satellite imagery, and other GIS data into the mapping environment.

As vast amounts of regional, geoscientific data are collected and made available online, these integrated methodologies have become essential to seeing the full picture, and gathering the multi-dimensional insight required to target subsurface exploration projects.

Integrated techniques, combined with more advanced 3D visualization capabilities, can also make old datasets and knowledge relevant for new projects and incoming geologists.

Integrated approach keeps mineral projects on track

Faced with the daunting task of narrowing down its exploration in Northern Ireland to establish drill targets, Lonmin is integrating geochemical and geophysical datasets with incoming data from its own exploration program to confirm they are working in the right area and keep their exploration strategy on the right path.

Maximizing insight for oil and gas exploration

Being able to better integrate potential field data with other kinds of geophysical and geological data has been key to the oil exploration work of Geophysicist Mark Longacre. With today's software and technology, integration from the gravity and magnetic world to the seismic world is seamless. Data and maps can be easily shared and used in GIS, petroleum systems software and seismic workstations.

Integrated techniques detect new mineral potential

Several Canadian Geological Surveys are working together to conduct mapping and lake sediment sampling aimed at uncovering new mineral potential in established areas. Integrated analysis techniques are being used within GIS to investigate the geochemistry of existing drill holes in order to piece together a map of the subsurface that – in combination with the geology and geophysics - will serve as a guide to further drilling

Data integration key to raising mineral discovery rates

While spending goes up, discovery rates in mineral exploration continue to decline. Closing the discovery gap is possible, says Professor Bill Morris of the School of Geography and Earth Sciences at McMaster University, but only if explorers begin to integrate geoscience information in such a way that they can see through rock and overburden to find buried deposits.
